Vedclass · Answer

(C) The movement of colloidal particles towards the anode indicates that the sol is negatively charged. According to the Hardy-Schulze rule,the coagulating power of an electrolyte depends on the valency of the ion carrying a charge opposite to that of the colloidal particles. Since the sol is negative,the coagulating power depends on the charge of the cation ($Na^+$,$Ba^{2+}$,$Al^{3+}$). Greater the charge on the cation,higher is its coagulating power. Thus,the order of coagulating power is $Al^{3+} > Ba^{2+} > Na^+$,which corresponds to $AlCl_3 > BaCl_2 > NaCl$.

$A$ colloidal solution is subjected to an electrical field. The particles move towards the anode. The coagulation of the same sol is studied using $NaCl$,$BaCl_2$,and $AlCl_3$ solutions. Their coagulating power should be:
